how to suppress an old linux fedora when installing a new one?

Thursday, 5 January 2017

Bonjour,

I want to install a new f25 on 2 disks using RAID 1.

I have an f24 installed on one disk and I want to suppresse it.

Anaconda shows this install as "Unknown linux system"(????). I tried to
suppress all partitions of this install using the "-" button, but this
fail. And after reinitialization of the disks, these partition are still
there and the sda disk as only 300Gb free while the new disk (sdb) has
1Tb free.

How to proceed to erase the old f24 install?

Thank you.
